I'm having the first few mods done on my 03 type S this week by yosolo in northern Jersey. I'm having new intake, headers, and exhaust put on (in addition to getting a kpro and tune). One thing that I'm a bit concerned about is that I will no longer have a cat. He's telling me that I...

What do I need to make this built possible (fuel wise) I know I will upgrade injectors, and fuel pump. Ultimately, get a fuel rail and a fuel pressure regulator as well. My main concern is the fuel lines, fittings, etc. I have no clue on that stuff. I know the RSX has some type of...

What's the minmum I can get away with for the K-pro? I'm thinking that the datalogging would be the most intensive app with the K-pro. Can I get away with one of these used 500 dollar laptops?
